9209Re: digipeat own packets when backpacking
- Nov 3, 2009So, wouldn't the solution to avoid spamming the network be:
1) turn off the Digi feature while driving and then turn it on when parked.
2) use a low-gain or directional antenna so that that the range of signals your digi picks up is local. This will minimize what it hears to the area surrounding your car. Pick an antenna gain that matches your local transmitter and the surrounding area.
Another option would be to crank up the squelch so that only strong, local signals are recieved.
3) use a high-power transmitter to kick the digipeated packets out to another digipeater or iGate. Adjust the TX power so that the signal goes as far as it needs to, but no more than it has to.
4) monitor the packets received to see if yours is among those digipeted by the wide2 digi. If you use a WIDE1-1,WIDE2-1 path in your beacon (VX-8R) and a WIDE1 digi in your car, your digi should still hear the packets that have been repeated by the WIDE2 digi, but it shouldn't repeat them. Or, you could have someone watching the APRS-IS to see if your packets are showing up in the net.
5) if you want to be extra conscientious, you could test the area where you park to see if there's already a WIDE1 digi that's covering where you are. e.g. see if the packets sent by the VX-8R are being digipeated by another digipeater. If so, leave your Digipeater off and use the existing one. If not, turn yours on and then it can be the one to fill in wherever you are.
